Absolutely
green with envy (as usual) that you were able to attend this fabulous event,
Jean-Luc. Looks like there were some quite rare vintage items on offer.
I've just come back from a short holiday to England. The closest I came to uncovering Playmo treasure was finding a second-hand, boxed Zoo set (3242) at a boot sale in Stafford.
At £4.00, it was quite reasonably priced, but I didn't buy it because the box was water-damaged and sealed with cellotape. Arghh!
Glad that you found something that made the journey to Luxemburg worthwhile!
